Answer 1

Answer:

a) all the corner cubes are painted green. so their are 8 cubes with 3 side painted green.

b) their is no cube having one face red and an adjacent face green as all the green painted cubes got paint on at least 2 faces.

c) let us calculate the number of cube with no painting: with formula, (n - 2) ^3=(5 - 2) ^3=27 therefore their are 125 -27=98 cubes having at least one face colored.
